Foucault's Pendulum 38cm rosie the riveter the girl learns everything sheThe Foucault's Pendulum is a simple pendulum apparatus with a sand bath at the bottom. When set in motion, it gently "writes" an ever changing geometric pattern. The patterns get bigger then smaller then bigger again as the arc of the pendulum also changes. You're sure to marvel at the geometrical designs that it comes up with! 14. 9" high (38cm). Ages 8 and up.
